Commuters [on a North Carolina highway] may find a new aroma commingling with exhaust fumes: The smell of grilled steak, coming from a billboard designed to entice shoppers by appealing to a sense other than sight … It pairs the smell with a big visual, showing a giant piece of steak and a French fry on a giant fork.
The post goes on to say that this is one of the first of its kind in the country. I was reminded by a friend this morning that the technique has definitely been enhanced by modern chemistry (by ScentAir of Charlotte, NC), but this tactic at least dates back to Wisconsin’s own Wienermobile.
… As if the vehicle’s design alone wouldn’t do the trick!
Can readers find an earlier example of out-of-home “whiff-appeal” to help sell a product?
